Abstract: With regard to two-way clock synchronous serial communication conducted between a back-end microcomputer 16 and a front-end microcomputer 8, data is sent from the front-end microcomputer 8 to the back-end microcomputer 16 in a form of responding to data sent from the back-end microcomputer 16 between the back-end microcomputer 16 and the front-end microcomputer 8 and from the sending side, sending target data formed by adding a byte for error detection to a byte which is the original sending target is sent and in the receiving side, when a byte corresponding to the byte for error detection is received, error detection of received data is performed using said byte and when an error is detected in the received data, by providing notification to the effect that a communication error occurrs from the receiving side to the sending side.

Abstract: It is supposed that recording of a drama program is started in accordance with recording reservation, and the recording is finished. If a program to be recorded next is a sports program, a message “Exchange the loaded disk with an optical disk for recording sports programs” is displayed on the display portion. When viewing this display, the user takes out the loaded optical disk for recording drama programs and loads an optical disk for recording sports programs to the device. When the recording of the sports program is finished and if a program to be recorded next is a language education program, a message “Exchange the loaded disk with an optical disk for recording language education programs” is displayed on the display portion. When viewing this display, the user takes out the loaded optical disk for recording sports programs and loads an optical disk for recording language education programs to the device.

Abstract: In an original image, an area whose brightness is smaller than a predetermined value is detected as an ink line area, and a neighboring area of the ink line area, which surrounds the ink line area, is detected as a neighboring area. Furthermore, with respect to an area other than the ink line area and the neighboring area in the original image, an outline portion of an image is detected as an outline area. A color is applied to the ink line area and the outline area, and a different color is applied to an area other than the above two types of area.

Abstract: When instructed by an input part 18 to perform CM skip, which is to skip CMs during a playback, based on mode change recording positions (addresses) recorded in a RAM 14b, a controller 14 confirms whether there is any recording position corresponding to a mode change in a 3-minute section, i.e., a normal air time of airing CMs since the recording position at which CM skip has been instructed, but when finding a recording position corresponding to a mode change, skips CMs up to this recording position. Meanwhile, when instructed for time/picture search during a playback, based on reference time point recording positions (addresses) recorded in the RAM 14b, the controller 14 skips to the closest reference time point recording position to the recording position at which time/picture search has been instructed and continues a normal playback operation.

Abstract: When a reproduction operation of data recorded on a recording medium is stopped, a stop position of the reproduction operation on the recording medium is obtained and stored in a position storage unit. Thereafter, when an input instructing resume reproduction is received, a time period elapsed from the time of stop of the reproduction is calculated. A resume position of the reproduction operation is determined with reference to the stop position stored in the position storage unit, based on the calculated time period.

Abstract: A seek control unit increments by a first magnitude the maximum speed when the pickup head is moved while the number of jumped tracks can be counted appropriately. If the number of tracks jumped during seek could not be counted appropriately, the seek control unit decrements the maximum speed by a second magnitude. The seek control unit sets the maximum speed stored in a speed information storage device 8 for a marginal speed. Once set for the marginal speed, the seek control unit, even when the number of jumped tracks can be counted appropriately, does not execute updating of incrementing the maximum speed stored in the speed information storage unit.

Abstract: In an original image, an area whose brightness is smaller than a predetermined value is detected as an ink line area, and a neighboring area of the ink line area, which surrounds the ink line area, is detected as a neighboring area. Furthermore, with respect to an area other than the ink line area and the neighboring area in the original image, an outline portion of an image is detected as an outline area. A color is applied to the ink line area and the outline area, and a different color is applied to an area other than the above two types of area.

Abstract: For enabling a stable clock signal to be extracted from even an input signal of which the duty factor is made worse, there is presented a clock extraction circuit applicable to an optical signal receiver equipped in an apparatus for use in the optical data communication. The clock extraction circuit includes a rising edge differential circuit (12) for differentiating the input signal at the rising edge thereof, a first monostable multivibrator (13) for processing the output from the differential circuit (12), a second monostable multivibrator (14) for processing the output from the first monostable multivibrator (13), an OR gate (15) for carrying out the logical OR between the output signals from the first and second monostable multivibrators (13) and (14) and circuitry for variably varying output pulse width, which processes the result of the logical OR.

Abstract: A rotation direction detecting apparatus including: a turntable 4 mounted on a rotary shaft 3 of a motor 2 and provided with a predetermined signal pattern, the predetermined signal pattern being formed so that reflection of light and non-reflection of light are repeated alternately and continuously by rotation of the motor 2; a photo-detector 5 for detecting the signal pattern of the turntable 4; and a micro-computer 7. The signal pattern is set as a pattern in which high-level regions and low-level regions are repeated alternately at a 2:1:1:2 ratio.
